LP3907QTL-VXSS/NOPB

Overview

The LP3907QTL-VXSS/NOPB is an automotive-grade PMIC featuring two synchronous buck converters and two LDOs. It operates within a 2.8V to 5.5V input range and supports switching frequencies up to 2.1MHz. The device provides outputs of 1A, 600mA, and 300mA with integrated sequencing. It is housed in a 25-WFBGA package and functions reliably between -40°C and 125°C.

Feature Summary

• Automotive AEC-Q100 qualification for high reliability
• Integrated dual synchronous buck and dual LDO topology
• Built-in power supply sequencing logic

Applications

• Advanced application processors
• FPGA core voltage regulation
• Generic embedded systems requiring multi-rail power

Procurement Notes

Verify the specific suffix VXSS against the official datasheet to confirm the exact output voltages and current ratings, as these parameters vary across the LP3907 family. Ensure the WFBGA-25 footprint matches your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when an automotive-rated solution is required for complex multi-voltage architectures. It consolidates multiple discrete regulators into a single package, reducing board space while maintaining high efficiency through synchronous buck technology and low-noise LDO performance.

Part Context

This part belongs to the LP3907 series of specialized PMICs designed for demanding applications. It integrates high-current step-down DC/DC converters with linear regulators, offering a compact solution for powering advanced digital logic and memory components in constrained spaces.

Replacement Considerations

LP3907SQ-PJXIX/NOPB shares similar functional blocks but differs in package type (WQFN vs WFBGA) and operating temperature range (-40 to 85°C). Verify thermal management and pinout compatibility before substitution.
